Clean and close to many things. Just very simple accommodations. No refrigerator, which I didnt realize, so I had to keep insulin on ice all day and night. Other than that, ok.

The property and rooms need some love. The carpet looks dirty, the bathrooms need a touch up all around (shower head had heavy calcium deposits, shower wall liner had visible tears, tile grout looks grimy). The laundry room - the washer looks like no one has cleaned it since they were installed. The software used requires you to fund your "account" and your choices are $10, $25, $50 - each wash or dryer use is $4 so you'll likely leave an unused balance. The staff was friendly and helpful. I wish their hospitality reflected in their rooms and property overall
